Figure caption: Maps of polarization segments rotated by 90° to show magnetic field orientation in Mon R2. The right panel shows a zoomed-in map of the region marked with a blue box in the left panel. The background gray-scale image shows dust continuum emission at 850 μm. The intensity scale of the image is shown as a color bar. The polarization segment selection criteria are I/δ I ≥ 10, p/δ p ≥ 2, p < 20%, and δ θ obs < 15° (definitions of I, p, δ I, δ p, and δ θ obs are given in the text). The coral and cyan segments correspond to measurements for which p/δ p ≥ 3 and 3 > p/δ p ≥ 2, respectively. The segments shown are binned to a 12″ pixel grid. The lengths of the segments are scaled to p and scale bars with p = 10%, and 1% are shown in the upper right corner of each panel. Yellow stars indicate the position of IRS 1 (R.A.(J2000) = 06h07m46.ˢ2, decl.(J2000) = −06°23′08″.3). The circles in the lower right corner of each panel show the JCMT beam size of 14″.1 at 850 μm. Physical scale bars at the distance to Mon R2 of 830 pc are shown in the upper left corner of both panels.
